The Topaz War Relocation Center, also known as the Central Utah Relocation Center (Topaz), was a camp which housed Nikkei -- Americans of Japanese descent and immigrants who had come to the United States from Japan. There were a number of such camps used during the Second World War, under the control of the War Relocation Authority. The camp consisted of 19,800 acres (8,012.8 ha), nearly four times the size of the more famous Manzanar War Relocation Center in California. Most Topaz internees lived in the central residential area located approximately 15 miles (24.1 km) west of Delta, Utah, though some lived as caretakers overseeing agricultural land and areas used for light industry and animal husbandry.
